Have to pick the side of the trailer up high enough to let the tire drop lower. Might have to put some pry force on the arm behind the wheel to push it down if the wheel won't drop from it's own weight
. When my axle
was replace the shop said the could pry the torsion arm down with a big (12 inch) screw driver because it was so worn.
Typical problem when the axle
suspension is really worn and the tire is sitting too high in the wheel well. Trailer rides low and tire is hard to get out of the wheel well.
Really important to have solid jack stands supporting the frame if trying to pry the torsion arm down or even just struggle with pulling the tire down far enough to clear the wheel well.
